I would love to have a big cardboard printed box that would hold the game (I know it's a digital game, but still).
Like those old school classic big box games, so that it would fit on my shelf between my classic game collection.
Stuffed with factorio goodies, like cheatsheets, decals, stickers and all that stuff.

Hell, I'd design it, have it developed professionally if the developers would ask me to.

Blender can produce a paper cut version of a model that you then fold and glue together. I bet it can also have the right textures on that flat version. Should make it quite easy to make a big cardboard printed box of an assembler.

Imagine this, the animals that ravage your base can lavish up your house. An adorable plushie variant of the bite and spiters, that can be bought straight off of the Factorio website and shipped directly to your house, who wouldn't want to buy one?

And I want to be reminded about new and discounted skins with a popup every time the game starts. Perhaps add a 5 second delay until the popup becomes closeable, to avoid closing it accidentally before looking at it.
